My present invention relates to reeds and more particularly to an. improved reed for use in weavers looms: having dents which are not only flexible but which are adapted to move slightly 5 .in and out at their end portions where they are held in place in the reed frame.

Heretofore, it has been the practice to construct reeds so that the dents could not slide longitudinally on their major axis but could be )slightly flexed by means of spring windings and various other means. Most reeds of conventional construction are provided with dents the ends of which are fixed in the reed frame by means of solder. Such reeds present a very 15.- limited amount of iieXibility and are easily bent or broken in use. One of the diiliculties of the soldered reed is the fact that it cannot be easily repaired due to the fact that it is necessary to unsolder portions of the reed where dents 20.",are to be replaced. This is a slow and laborious process. Furthermore, in most reed construction, hand labor is a necessary facto-r which naturally adds greatly to the oost of production.

In my present invention, I have obviated these difficulties and objectionable features and have developed a new reed which isV not only much more inexpensive and simple to construct but is also more exible; can be easily repaired, and assembled by machine Without the aid of hand labor.

The principal object of my invention is an improved reed for weavers looms and the like;

Another object is an improved reed having dents free to move longitudinally of their major axis;

Still another object is an improved reed which provides positive holding and alignment means for the dents without the use of solder, pitch or other binders of a similar nature;

Still another object is an improved reed the dents of which are readily removed and replaced without disturbing the windings or other dents;

And still another object is an improved reed having dents which are frictionally held in place;

A still further object is an improved reed which is provided with means for automatically maintaining the slidable den-ts in alignment, and

Other objects and novel features comprising the construction and operation of my improved reed will be apparent as the description of the same progresses.

In the drawings illustrating the preferred embodiment of my invention; Fig. 1 is a side elevation of an assembled reed in which my invention is present, the central portion of which is broken away for convenience; y

Fig. 2 is an end elevation of Fig. 1, the end of the upper frame being leftunnished to better show the relation of the various parts;

Fig. 3 is a fragmentary enlarged side elevation of the upper left-hand corner of Fig. l, the guard casing having been slid back to better show .the construction;

Fig. 4 is a plan View of Fig. 3;

Fig. 5 is a greatly exaggerated enlargement of a typical section of the reed showing the action of the dents when a knot in the warp passes through the dents;

Fig. 6 is a cross-section taken on the line 6 6 -of Fig. 3;

Fig. '7 is a perspective view of a cap member which fits over the ends of the frame of the reed under the guard casing, as shown inV the lower side portions of Figs. 1 and 2;

Fig. 8 is a cross-section similar to Fig. 6 but showing strips Illa. formed from semi-tubular shapes;

Fig. 9 is a fragmentary side elevation of thev upper left-hand corner of Fig. 3, the guard member i5 being removed, and showing one end of the dents I3 being soldered together, and

Fig. l0 is another modication similar to Fig. 9 except that the ends of the dents are'not all soldered together at their extreme ends, as in Fig. 9, the dents I3 beyond the. soldered portions 2li being free to slide between the wire I4.

Referring more in detail to the drawings, lil indicates two half-round strips on they topr and bottom sides of the reed, the ends of which are separated by means of the bars II. The bars and strips are tightly bound together by means of the pins l2 which pass through the strips I0 and the bars Il.

At I3, I have shown a plurality of dents,V the ends of` which pass between the fiat sides of the half-round strips Ill projecting out beyond the strips approximately the same distance` as the ends of the bars II. the dents are shown with their narrowedges in elevation except inFigs. 2, 6 and 8 vwhere the broad side is shown in elevation'. In Fig. 2, it will be observed that the narrow sides of the dents extend slightly beyond the sides of the bars I l. This is important as it produces the In all the viewsillustrated -1 friction necessary between the strips I0 and the v dents I3 when the reed is assembled, as shown in Fig. l.

At Ill, I have indicated a wire, ,the end of which, is anchored in the end of the bar-| Il,l as

shown in Figs. 3 and 4. This wire I4 is Wound around the strips i0 ,and between `the dents I3 modication, at 20, I have indicated the dents as being soldered together on their ends. 'Ihe solder 20 also connects the wire I4 at these points. Preferably the strips II are not bonded to the wire and dents as the wire and dents are made of steel while the strips are preferably made of aluminum. The ends of all the other dents between this point and the last several on the other end of the reed are left free as in Fig. 3. This arrangement prevents any possibility of Ithe wire becoming freed at the end of the reed and the accidental release of the dents.

In Fig. 9, I have carried this step further and in addition to bonding the wire at the end of the reed with several of the dents, as in Fig. 10, I have also bonded together at 2|, the ends of all the reed dents on one side of the reed but not the wire except of the rst several dents from the ends of the reed.

In Fig. 8, I have shown a hollow tubular halfround strip Illa. In this construction the friction contact surface between the dents and strips is greatly reduced.

With my preferred construction, a damaged dent may be pulled out of the assembly, as shown in dotted lines, with a pair of pliers and a new dent inserted in a short matter of a few seconds.

At Fig. 5, I have illustrated, in exaggerated scale, the action of the dents I3a, I3b etc. when the dents are passing over a knot in the warp, special attention being directed to the withdrawn end of the dents, Dents I3a and I3b slide in the strips I0 and between the wire I4 returning to their normal position after the obstruction has passed through the dents. Any other operation of the loom operator which requires the spreading of the dents causes them to operate in the same manner. It will be noted that with this construction, there is very little strain placed upon the dents which can produce a permanent set in the metal. As a matter of fact, these dents may be spread to a much greater degree than is possible in reeds in which the dents are rigidly fixed in the strips and frame. For the purpose of maintaining the dents in alignment and to prevent them from creeping in one direction, I have provided the guard casing I5, better shown in Figs. 2 and 6. This casing I5 consists of an open sided tubing provided with a channel portion I6 which is adapted to t over the ends of the dents I3, as shown in Figs. 2 and 6 and which prevent the dents from working out of engagement with the strips and spring coils. While the wire I4, to a limited extent, may have certain spring eiects its prime action is more in the nature of a binder to tightly bind the strips and dents together and at the same time space the dents.

Cap members I'I are tted over the ends of the assembled strips and bars and the casing I5 slides over the caps, the slots I8 in the caps engaging over the bars II. After these elements have been assembled together, as shown in theV upper left-hand corner of Fig. 1, the end is iilled with solder, as shown at 20 thereby binding the connecting units together.

It will thus be seen that I have designed a very simple and eicient reed which is extremely flexible in operation and which lends itself to quick repair and while I have shown my preferred form somewhat in detail yet it is to be understood that I may vary the design or proportions or make other alterations and changes all of which are within the spirit of the invention within wide limits.
